Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

Addressed issue where the Universal CRT _splitpath was not handling multibyte strings correctly, which caused apps to fail when accessing multibyte filenames.

Addressed issue where the Universal CRT caused the linker (link.exe) to stop working for large projects.

Addressed issue where the MSMQ performance counter (MSMQ Queue) may not populate queue instances when the server hosts a clustered MSMQ role.

Addressed issue with the Lock Workstation policy for smart cards where, in some cases, the system doesn’t lock when you remove the smart card.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

Windows Update Client Improvement

Microsoft will release an update directly to the Windows Update Client to improve Windows Update reliability. It will only be offered to devices that have not installed the most recent updates and are not currently managed (e.g., domain joined).
